Your Heating Questions Answered by AA Service Co. Experts
Heating FAQs: Answers from Our Chicagoland HVAC Experts
Whether you’re wondering when to replace your furnace, how often to schedule maintenance, or what’s included in a tune-up, we’ve got you covered.
How much does it cost to install an entire HVAC system?
We strongly recommend a professional maintenance check and tune-up for your furnace or boiler once a year. The ideal time is in the fall, just before you begin relying on it for the cold season. Annual service ensures your system runs safely and at peak efficiency, which can lower your energy bills, prevent unexpected breakdowns during the coldest winter days, and significantly extend the lifespan of your equipment. It is the most effective way to protect your investment and ensure your family’s comfort.
How often should HVAC be replaced?
NATE (North American Technician Excellence) is the gold standard for certification in the HVAC industry. A NATE-certified technician has passed rigorous, real-world exams, proving their expert knowledge of heating and cooling systems. When an AA Service Co. technician arrives at your door, you can be confident a highly qualified and tested professional is caring for your home’s comfort system.
Do I need to have my HVAC system serviced every year?
Yes! We know that heating systems can fail at the worst possible times. That’s why we offer 24/7 emergency heating repair services across Chicagoland and the North Shore. Call us anytime, day or night, and we will dispatch a technician to restore your heat.
What are the most common heating problems?
A furnace is a forced-air system that heats air and distributes it through ductwork. A boiler heats water, which creates steam or hot water that moves through pipes to radiators, baseboard heaters, or radiant flooring. We are experts in repairing and installing both.
What is included in HVAC maintenance?
Since 1965, our family-owned business has been built on trust, expertise, and a commitment to our community. We provide NATE-certified technicians, transparent flat-rate pricing, and a 100% satisfaction guarantee on all our work. We don’t just see you as a customer; we see you as a neighbor. That’s the AA Service Co. difference, and it’s why generations of Chicagoland families have trusted us to keep their homes comfortable and safe.
What does a furnace tune-up include?
Start with an annual professional tune-up to ensure your system is running at peak efficiency. Additionally, change your air filter regularly (every 1-3 months), seal air leaks around windows and doors, and consider installing a smart thermostat to optimize your heating schedule.
